Why do we have "The LORD" in our bibles rather than Yahweh?

This is a very common question. It all began with a Jewish tradition
called the "ineffable name" doctrine.
Jews, for various reasons, started to substitute His name with the Hebrew title "Adonai". Adonai
is the Hebrew word for "Lord". This information can be easily verified
in many Bible dictionaries and various encyclopedias. For instance, the
Encyclopedia Britannica states:

Yahweh,
the God of the Israelites, his name being revealed to Moses as four Hebrew CONSONANTS (YHWH) CALLED THE TETRAGRAMMATON. AFTER THE EXILE (6TH
CENTURY BC), and especially from the 3rd century BC on, Jews ceased to
use the name Yahweh for two reasons. As Judaism became a universal religion
through its proselytizing in the Greco-Roman world, the more common noun elohim,
meaning "god," tended to replace Yahweh to demonstrate the universal
sovereignty of Israel's God over all others. At the same time, the divine name
was increasingly regarded as too sacred to be uttered; it was thus replaced
vocally in the synagogue ritual by the Hebrew word Adonai ("My
Lord"), which was translated as Kyrios ("Lord") in the
Septuagint, the Greek version of the Old Testament.

We see in the above quote that Jews started to vocally replace the name
"Yahweh" with "Adonai" (Lord) for two reasons:

1. It was beginning to be believed that His name was too sacred to be
uttered

2. They preferred to simply call Him "Elohim"
rather than "Yahweh" to demonstrate to the world that He is the only true
Elohim.

While on the surface these reasons may seem honorable, they are very
unscriptural. They were and are attempts to improve on Yahweh's already
perfect ways. If Yahweh really wanted a substitute, why would He have placed His
name there to begin with? Though scripture says to follow Yahweh rather than
man, we find that nearly 7,000 times the most important name of all is replaced with a
another word that man has chosen.

This tradition was not
practiced by the Messiah or the apostles, but it was adopted by some
Christians
during the early half of the 2nd Century CE/AD. By the 4th century, this
practice was well established and widely practiced. Jerome,
a 4th century "Church Father" who authored the Latin Vulgate version, substituted
the name "Yahweh" throughout with the Latin word "Dominus" (meaning "Lord").
The tradition of replacing Yahweh's name with "the LORD" continues to this day.
Most English translations substitute the name Yahweh with "the LORD" and
translations into other languages will also commonly choose a title meaning
"Lord" in their own language. More information on this can
be found in the preface of many
modern bibles.
